Description

[Detailed Description of the Invention] This Bonmei is a drainage system suitable for use in intensively removing drainage water from the lower part of windows, roof canopies, floors, etc. of vehicles such as automobiles or buildings. Concerning how to remove a pipe.

For example, when installing a drain pipe at the bottom of a car window (Method J), a drain hole is drilled at the bottom of the windshield fitting groove of the weather strip, and a drain hole is drilled on the panel side of the vehicle body facing the drain hole. A widely used method is to fix a water guide pipe to the IJI water hole, insert and extend a drain hose, and cover the drainage outside the vehicle.However, with the above conventional method,
Clamping the drain hose must be done from the back of the narrow interior of the car, which is very inefficient and undesirable from the standpoint of reducing man-hours.Also, the position of the drain hole is not necessarily ideal due to the need to take up clamping space. There was a problem that it was not possible to set the position.

Therefore, in order to deal with the above-mentioned problems, the present invention eliminates the conventional clamping work and sets the drainage hole at an ideal position. □? Soft S' [il
l Connect the water to the fitting part; close the fitting part of the soft drain pipe C.
A bulging strip is formed on the outer periphery of the body of the center rib 1. A soft 1) F light blue is attached to the periphery of the drainage hole to tighten the hollow rivet.
At the time of lil, the close contact IJ-1-especially J-4, which has a famous waterproof effect and work efficiency.
.

The present invention will be described in detail with reference to the drawings and embodiments.

Figure 1 to Figure 5
Examples of application are shown in Figures 1 and 2 (a first example in which a hollow rivet 1 to C1 is inserted across J drainage J1., and a soft drainage pipe is inserted with a small force, and Figures 3 to 5). The figure does not show the second embodiment in which a soft IJi water pipe is fitted to the outer periphery of the body of the hollow rectifier 1 to the drain hole. In the second embodiment-C

1 kl], the periphery of the drainage hole 21 is maintained in a completely watertight state, and no water leaks from there. Even if water leaks from the wind seal [~], the soft water will definitely be drained out of the vehicle body through the hollow part 32 of 1↑(3). It is effective in reducing costs by sealing around the periphery of the car and replacing the small scrap.In addition to the narrow back inside of the car, this small scrap can be omitted and the drainage pipe can be removed (4).
The work is extremely easy (easier and safer).

413 In the second embodiment shown in FIG. 41 to FIG.
1, the soft drain pipe 3 is fitted in advance to the outer periphery of the body 72 of the hollow rivets 1 to 7. Next, the soft drain pipe 3 is inserted into the drain hole 22 in the vehicle body panel 1 from one side, and the mandrel 8 is inserted into the screw threaded part 73 of the hollow rib 11-7 as shown in FIG. To L-tsu 1, mandrel 8

3. According to this h method, is there a soft drainage? By inserting the open end 31 of the drain hole 22 into the drain hole 22 and crimping it at the same time, the open end 31 of the drain hole 22 is crimped and automatically attached to the lower surface of the periphery of the drain hole 22. Target (obtained the effect of IJ II- without J, 741
Keep the periphery of the water hole 22 in a completely cooled water ratio and prevent water from leaking from there. In addition, the hollow rivet 1-7 serves as a seal around the periphery of the drainage hole 22 and as a substitute for a small scrap.It is effective in reducing stress. The water pipe 3 is fitted into the drain hole 22.
-1) Since it is inserted from the inside of the car, there is no need to work in the back of the car, which is a narrow space that cannot be seen with the naked eye, making the work easier and safer, which is extremely effective.

If hollow rivets 1 to 7 (female screws (=J, hollow spatula 1 to 1) are used as in this example, the management using 2 rivets and 1 herk becomes more efficient, and the effect of waterproof maintenance 81F can be improved. Sai,.

(k-As explained above, according to the present invention, the soft drainage t1 is directly attached to the periphery of the drain hole M at the time of caulking and 1ij at the middle edge and 1ij to ensure hardening, thereby improving the hardness of the conventional method. Compared to conventional clamp tightening, the work is easier and the waterproofing effect is much greater, and the conventional waterproofing function can be achieved without using a sealant.
